Ecology & Habitat
Description
Smooth buckwheat is a small annual that often branches at the base. Its stems up to 15 cm high. The mainly basal leaves are 5-30 mm long are and spoon-shaped with a broad petiole, while the stem leaves may be sessile. The foliage is glabrous. The small yellow flowers have 6 lance-shaped perianth segments that are 1-3 mm long. Flowers are borne in a cup formed of 2 whorls of 3 tiny bracts each, or an involucre. The involucres are borne in an open, dichotomously-branched inflorescence located at the top of the stem. The seeds are ca. 2 mm long.
Diagnostic Characteristics
This species can be distinguished from other annual members of the genus by the involucre composed of 2 whorls of 3 bracts each. A hand lens is necessary for positive identification.
Habitat
Shadscale, mat-atriplex & pinyon-juniper communities (Welsh et al, 1987).
